The BBC are reporting that the Northern Ireland Policing Board have been told that they must improve security at their Belfast headquarters. Presumably on the advice of MI5… There was an attempted car-bomb attack on the building in November last year. From the BBC report

The PSNI believe there is a substantial risk of another attack on the building. They have warned that security needs to be improved. At a special private meeting of the Policing Board on Thursday, members were told of a number of options. They include making the area around the building a pedestrian zone, spending about £2m to bomb-proof the building, and even moving to new offices in a more secure location.
